代码执行批量Excel数据导入Oracle数据库

由于基于Oracle数据库上做开发，因此常常会需要把大量的Excel数据导入到Oracle数据库中，其实如果从事SqlServer数据库的开发，那么思路也是一样的，本文主要介绍如何导入Excel数据进入Oracle数据库的内容。

方法一：

1.准备数据:在excel中构造出需要的数据
2.将excel中的数据另存为文本文件(有制表符分隔的)
3.将新保存到文本文件中的数据导入到pl*sql中
在pl*sql中选择tools--text importer,在出现的窗口中选择Data from Textfile,然后再选择Open data file,
在弹出的文件选择框中选中保存有数据的文本文件，此时将会看到data from textfile中显示将要导入的数据
4.在configuration中进行如下配置
注:如果不将Name in header勾选上会导致字段名也当做记录被导入到数据库中，从而导致数据错误
5.点击data to oracle，选择将要导入数据的表，并在fields中将文本中的字段与表中的字段进行关联
6.点击import按钮进行导入
7.查看导入的数据
OK,至此数据导入成功。

方法二：
 String fileName = "F:\\xx.xls";  //"F:\\document/test/aa.xls";

 public static void createBusinessFinish(String fileName) {

        try {
            //申办
            EntitySet<laam_ex_sb> sbSet = getExcelSBdata(fileName);
            List<laam_ex_sb> sblist = null;
            if (sbSet != null) {
                sblist = sbSet.getResult();
                for (int i = 0; i < sblist.size(); i++) {
                    laam_ex_sb sb = sblist.get(i);
                    sb.setID(Global.getInstance().GetUUID());
                    String sbStr = Global.getInstance().getSerializService().Serialize(sb);
                    EntityBean bean = (EntityBean) Global.getInstance().getSerializService().DeSerialize(sbStr, EntityBean.class);
                    bean.setbeanname("laam_ex_sb");
                    bean.insert();
                }
            }
    }
